unshelve: add abort on using continue and interactive together

`unshelve --continue --interactive` will not work as expected by the
user as the mode of in-progress unshelve is preserved and cannot be
overwritten. This patch makes `unshelve` to throw an error on using
both `--continue` and `--interactive` together with `unshelve`.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
