REGTESTS: proxy: complete "del backend" test

A recent fix was introduced for "del backend" on 3.4 when deleting the
first proxy declared in the configuration. This issue does not affect
the current development tree.

To ensure this case is safe, complete backend deletion reg-test with a
deletion on the first declared proxy. This could prevent any future
regression for this particular case.

This should be backported up to 3.4.
