This commit replaces `os.MkdirTemp` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `os.MkdirTemp`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

In some instances the communities migration would be skipped but not
marked as `dirty`.
This commit addresses the issue by:
- Making sure that if dirty is set the migration is not skipped but
replayed
- If the version is on the communities migration and dirty is false, we
check for the presence of the communities table. If not present we
replay the communities migration.
- Make community_id field in user_messages nullable
It also removes all the `down` migration, as we can't use them
effectively, as explained in the README.md added.
