share: backout fd903f89e42b, except the test

Locating the share source when no default path is available is now handled in
subrepo._abssource(), so unconditionally setting a default path (and the
associated problems) can be avoided.

The test change reflects the fact that a default path is no longer set on the
resulting share.
