wlock: reword the devel warning

We change the wording of the developer warning:

  -  "lock" taken before "wlock"
  +  "wlock" acquired after "lock"

The goals here are to:

- Put the "subject" as the first word,
- use "acquired" instead of "taken" since it seems more accurate.

"""test behavior of propertycache and unfiltered propertycache

The repoview overlay is quite complex. We test the behavior of
property cache of both localrepo and repoview to prevent
regression."""
