revlog-split: also check a case where bundle contains multiple changegroup
This case is not affected, we remains in the same transaction. However it seems
important to improve the test coverage around these "features". It also helped
to assert the scop of the critical bug.

Function to check that statprof ran

Profiling of HTTP requests works

A single profile is logged because file logging doesn't append
