[erp5_web_renderjs_ui] If service worker failed to install cache, unregister this service worker explicitly.

The name must be different per web site, else if the same service worker code is used by multiple web sites in ERP5 web site module, service worker does not work correctly.

[erp5_web_renderjs_ui] Fix translation script. Get service worker filename from layout property. Don't hardcode it.

[erp5_web_renderjs_ui] New client can use the latest cache without waiting for the new service worker to be activated.

And once client was associated with a cache, client keeps using the same cache.

To preserve the consistency of code and data, let the new service worker wait until all tabs and windows of the old version are closed.

Don't give request object itself to cache.match. Firefox's Cache Storage does not work properly when VARY contains Accept-Language. Give URL string instead, then cache.match works on both Firefox and Chrome.

[erp5_web_renderjs_ui] Fix rjs_gadget_erp5_serviceworker.js. Use cache.add because safari does not support cache.addAll.

Collect a list of files from service worker code.

Fetch usage can be bypassed to do not use service worker when not needed.

As appcache has been dropped on Firefox, this change will improve the speed on Firefox.

No change is expected on Chrome/Safari.

erp5_trade: Fix PackingList_getODTDataDict.py. Get source reference from supply paths. Movements are not predicates.

Otherwise, this test fails because of duplicate uids.

Display precalculated listbox content returned after a form validation
error.

Ensure the cell error_text is displayed and can be removed.

Return the submitted value in case if present in the REQUEST.

Return the cell error_text if present.

Execute the listbox listmethod in case of ValidationError.
Ensure that it is rendered with the same query parameters.

This commit does not change the behaviour of the gadget.

The goal is only to make the next commit more readable.

Even if it does not lead to ConflictError being raised, updating _max_uid
has a cost and a transaction-serialising effect (most noticeable with NEO).
This value is not used (outside of a bootstrap value for portal_ids
generator), so stop doing this unnecessary work.
Also, fold produceUid into its only caller.
Also, change the folded pattern to react to an empty buffer rather than
test for emptiness before each access.

The way of truncating the index file was an error in git 2.11.0, but it
was not an error with git 2.17.0.

Follow xhtml_style CSS.

This is nearly a copy/paste of renderJS error rendering.

While rendering a field_list gadget in non-editable mode,
the `text_content` parameter was given only in the first `render` call.

Before we were using up to 10 testnodes per test suite. Push it to 15 testnodes to have
chance to run big test suite (like whole ERP5 tests) in less than 2 hours.
