tests: stabilize `test-transaction-wc-rollback-race.t` on Windows

MSYS has a tendency to munge C:\Dir\SubDir\File into C:DirSubDirFile unless it
is quoted, and that's what was happening here- there were a lot of these
failures:

    file not created after 5 seconds: $TESTTMP/transaction-waiting

I suspect quoting is only needed in the hook script that is generated (the
catting of the log file pointed me in the right direction here), but I missed a
spot and trial and error got me here.  The quoting elsewhere doesn't harm
anything and it was taking 7+ minutes to run this test when things were timing
out, so I don't feel like reducing the quoting to the minimum required.

 Check potential race condition around transaction and working copy data

 #testcases bookmarks-in-store bookmarks-wc-level
 
 The transaction is garanteed to run with the lock, but may runs without the
 wlock. So if the transaction backup/restore some content related to the
 working-copy and protected by the wlock, we might run into trouble if another
 process grab the wlock and modify them.
 
 This test file is testing various cases where such parallel changes happens to
 validate the transaction behavior.
 
 Other is used to get a simple pull source. As pull is a simple way to create
 transaction without the wlock.

 Check the overall logic is working, the transaction is holding the `lock` , but
 not the `wlock`, then get aborted on a signal-file.
