Add unique constraint back into issue_index (#16938)
There is a flaw in #16820 where it was missed that although xorm will
not add a primary key to a table during syncing, it will remove an
unique constraint.

Users upgrading from 1.15.0 to 1.15.1 will therefore lose the unique
constraint that makes this table work unless they run `gitea doctor
recreate-table issue_index`.  Postgres helpfully warns about this
situation but MySQL does not.

Main/1.16-dev is not affected by this issue as there is a migration that
does the above recreation by default. Users moving directly to 1.15.1
from 1.14.x or lower are also not affected.

Whilst we could force all users who ran 1.15.0 to do the above
recreate-table call, this PR proposes an alternative: Just add the
unique constraint back in for 1.15.x. This won't have any long term
effects - just some wasted space for the unnecessary index.

Fix #16936

Add primary_key to issue_index (#16813) (#16820)
Backport #16813

Make the group_id a primary key in issue_index. This already has an
unique index and therefore is a good candidate for becoming a primary
key.

This PR also changes all other uses of this table to add the group_id as
the primary key.

The migration v192 from #16813 has not been backported but Xorm will
work fine with non-primary keyed tables. If a user on 1.15 wishes to
have the correct schema sooner than 1.16 - they can use gitea doctor
recreate-table issue_index and gitea will recreate the table with the
primary key.

Fix #16802
