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.

===============================================
Testing content-divergence resolution: Case B.1
===============================================

Independent rewrites of same changeset can lead to content-divergence. In most
common cases, it can occur when multiple users rewrite the same changeset
independently and push it.

This test belongs to a series of tests checking the resolution of content-divergent
changesets.

Category B: parents are obsolete
Testcase 1: one side amended changes and other rebased to in-between successor of basep1
Variants:
# a: default resolution
# b: minimal resolution using `experimental.evolution.divergence-resolution-minimal=True`

B.1 Relocated backward; Rebased to parent's successor
=====================================================

.. (Divergence reason):
..    local: rebased to the 'in-between' successor of basep1
..    other: amended some changes
.. The default resolution here is that we choose the final successor as resolution parent,
.. but this behavior can be changed to use the 'in-between' successor as resolution parent
.. by using a config option `experimental.evolution.divergence-resolution-minimal=True`
..
.. This test case is considered complicated and can change its behavior acc. to the user
.. feedback. For more, please look at section 'D-A3.1' in troubles-handling.rst
