Fix failing migration on mysql

We didn't specify that the db user needs the right to create temporary
tables before. That's why the migration will fail on most installations
that installed gitlab according to our documentation. This MR removes
the "TEMPORARY" from the migration and changes the documentation to
include the necessary rights for the future.

Fixes #2590

See merge request !1351

Fix IssuableContext javascript

We were calling `affix` before the events were bound so they never
triggered correctly.

Closes #2597
