share: fix source repo lookup on Windows

The stored path contains platform specific separators, so splitting on '/.hg'
returned the string unmodified on Windows.  The source was then looked for in
$source/.hg/.hg, which obviously fails.  This caused cascading errors in
test-share.t relating to the recent bookmark support.
