cache-tree tests: use a sub-shell with less indirection
Change a "cd xyz && work && cd .." pattern introduced in
9c4d6c0297 (cache-tree: Write updated cache-tree after commit,
2014-07-13) to use a sub-shell instead with less indirection.
We did actually recover correctly if we failed in this function since
we were wrapped in a subshell one function call up. Let's just use the
sub-shell at the point where we want to change the directory
instead.
It's important that the "|| return 1" is outside the
subshell. Normally, we `exit 1` from within subshells[1], but that
wouldn't help us exit this loop early[1][2].
Since we can get rid of the wrapper function let's rename the main
function to drop the "rec" (for "recursion") suffix[3].
