Bug 33406: Handle ES search errors for authorities

We are dealing ok with ES exceptions for biblio records search,
catching them and raising them to the end user. But we don't for
authorities, where we explode with an ugly 500.

Test plan:
Search for "(term_1*) AND (-) AND (term_2*)" in the authority search and
notice that you don't get a 500 but an error instead saying that you
should try again
