* test: reenable tinymce tests

* fix: sets a default label

this mistake was highlighted by the test runner

* test: reenable tinymce tests

* build: ignores autogenerated test file

* build: adds github error logging to icon generator

* build: log as error

* build: adds tests for generate:* scripts

* build: optimises icons with svgo to remove useless things like comments

this also ensures that icons are unchanged when we upgrade icon library packages as they would normally include things like versions as comments in the files
