Some calls to $lang->has_phrase don't pass session parameter

[tmb]

Seen in: EPrints::Plugin::InputForm::Component::Upload::has_help

This doesn't cause a problem until a phrase is modified via Edit page phrases - now the call to _get_src_phrase without a session will fail:

[error] Can't call method "get_repository" on unblessed reference at /opt/eprints3/perl_lib/EPrints/Language.pm line 342.\n

=> user sees internal server error when trying to access Upload stage of workflow

Other instances:

EPrints::Plugin::InputForm::Component::Documents::has_help EPrints::Update::Views L566 L1345 L1400

Also applies to any call to $lang->get_phrase_info or $lang->phrase
