tests: fix glob pattern for dynamic timer alignment

The number of space characters varies depending on the number of digits of the
timer, making some tests fail on slow machines in an unintended way:

Hidden common predecessor of divergence does not cause crash

First create C1 as a pruned successor of C
  $ hg co C
  2 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg amend -m C1
  $ hg tag --local C1
  $ hg debugobsolete $(hg log -T '{node}' -r C1)
  1 new obsolescence markers
  obsoleted 1 changesets
Now create C2 as other side of divergence (not actually divergent because C1 is
pruned)
  $ hg co C
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg amend -m C2
  1 new orphan changesets
Make the common predecessor (C) pruned
  $ hg tag --local --remove C
  $ hg co C1
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
Try to cause divergence
  $ hg amend -m C11
  abort: cannot amend 2758767f5d17, as that creates content-divergence with bfcb433a0dea, from 26805aba1e60

Corner case of amend from issue6157:
- working copy parent has a change to file `a`
- working copy has the inverse change
- we amend the working copy parent for files other than `a`
hg used to include the changes to `a` anyway.
