undefined $username at load_login (TPAC)

[Dan Scott]

* Evergreen master / 2.7 / probably a long way back

Open-ILS/src/perlmods/lib/OpenILS/WWW/EGCatLoader.pm currently reads (around line 387):

     my $username = $cgi->param('username');
    $username =~ s/\s//g; # Remove blanks

This can throw an "Use of uninitialized value $username in substitution (s///)" warning in Apache logs if $username has no value at all.

See http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/dbs/lp1400082_avoid_uninit_username_in_login for a quick fix by assigning a default value of '' if the var is undef.

Picked to master, rel_2_7, and rel_2_6.
