topic: drop topicfilter usage from topicrepo.commitctx()

This block of code was introduced in 13313d0cab71, but the commit description
doesn't explain the exact intent of this code.

The fact that the result of other.commitctx() was discarded makes me think that
this block only existed to deal with amends, and it was only useful for code
that was removed earlier in this series.

The only code that's left in commitctx() is adding current topic to
workingcommitctx, and I don't think we need to adjust repo filter for that.
