\local_coursetranslator\output\translate_form::require_access possibly not used

[tmuras]

I think \local_coursetranslator\output\translate_form::require_access() function is not used.

Otherwise this will trigger an error:

moodle-local_coursetranslator/classes/output/translate_form.php

Line 191 in b8efe2c

require_capability('local/multilingual:edittranslations', \context_system::instance()->id);

as require_capability() expects context class as second argument, and there is an integer passed there (there should be \context_system::instance() instead of \context_system::instance()->id)
