Ramkumar Ramachandra 7f9a5fc687 t1510 (worktree): fix '&&' chaining ...

Breaks in a test assertion's && chain can potentially hide failures
from earlier commands in the chain.

'unset' returns non-zero status when the variable passed was already unset
on some shells; we need to change these instances to 'sane_unset'.
