Admin: wildcard searching on all filter text fields

[vohmar]

Currently the partial and wildcard search (%) is enabled only on domain field in domain listing (/admin/domains), name filed in contact listing (/admin/contacts) and domain version view (/admin/domain_versions), but it should be available on all filter fields that enable text search

• /admin/domains - regsitrant ident, contact ident, nameserver
• /admin/contacts - partial search missing on all text fields, wildcard working on all
• /admin/contact_versions - wildcard search missing on all text fields, partial working on all
• /admin/blocked_domains - partail search missing on name, wildcard works on name
• /admin/reserved_domains - partail search missing on name, wildcard works on name
• /admin/epp_logs - wildcard search missing on API user, registrar; partial search works
• /admin/repp_logs - wildcars search missing on API user, registrar; partial search works
