Fix error preventing displaying of commit data for a directory with a leading dot

Directories with leading dots erroneously get rejected by the route controller if git
ref regex is used in constraints. This prevents commit data from being loaded. The regex verification is now done in controller.

Closes https://github.com/gitlabhq/gitlabhq/issues/8763

Prevent a JS error in MergeRequestTabs

When `window.location.hash` is pointing to a note, e.g. `#note_1234`,
`scrollToElement` would throw an error because a selector such as
`.commits #note_1234` doesn't exist, so `offset()` returned `undefined`.

This error would prevent subsequent calls from running, which caused the
loading spinner to never be hidden.

Now we ensure the selector returns a valid element before trying to
scroll to it.

This is the proper fix for !1553.

This reverts commit b4639754.

Improve invalidation of stored service password if the endpoint URL is changed

A number of issues were found in !1490 and !1558 (triggered by support request 7395)

* It is not possible to set a new URL and a password at the same time (new password is ignored)
* An error occurs on the Service Templates admin pages (prop_updated? was referencing the service's project, which is not defined for templates)
* Passwords are reset on every save in Service Templates admin pages

This should fix these 3 issues by respectively:
* Differentiating a property that has been assigned a new value (regardless of the new value) and a property that has been assigned a new value that is different from the old one
* Providing an alternate implementation to detected updated properties, not relying on the service's project
* Filtering an empty password parameter passed to the Service Templates admin page like on the project service page
