Discourse: scope mirror tests as being "mode 1" (#1463) 

This is to prepare for mode 2 being tested side-by-side.

The normalizeMode1Topics function enforces bumpedMs is not
updated for mode 1 tests.

Additionally describe "update semantics" is redundant,
as the mirror has no other function than update.
