If any content type does not have a workflow, the module gives an error

Line 456 in 411e3f9

$moderation_state = reset($form_state->getValue('moderation_state'));

assumes that the content type has a moderation state associated.
There might be some content types that do not have a workflow associated.
When we edit such content and try to save - we get this error:
TypeError: reset(): Argument #1 ($array) must be of type array, null given in reset() (line 456 of /app/docroot/modules/contrib/tide_core/tide_core.module)

This issue can be fixed by wrapping this in isset()
