Bug 29173: Fixed pre-filling of the search form from the "Replace record with ZR39.50/SRU" (Authority page detail)

Now this action has the same pre-filling behaviour as the "Edit" -> "Edit Record" -> "Replace Record via Z39.50/SRU Search" action.
Author Personal - Author Meeting/Conf. - Uniform Title and Subject are filled in if the subfield contains data (like the "Edit->Replace" action).
Unimarc and Marc21 specificities are supported.

Test Plan :

1) You must have a Z39.50/SRU server for authorities
2) Go to an authority detail page (Author - Uniform title - Subject)
3)After go to "Edit"-> "Edit record" -> "Replace record via..." or
choose "Replace Record.." directly
4) See that form is also prefilled with data now
