Return value type is too hard (strict): FrontendUtility#getPropertyFromLoggedInFrontendUser(string $propertyName = 'uid')

[docmcfly]

The method \In2code\Powermail\Utility\FrontendUtility#getPropertyFromLoggedInFrontendUser(string $propertyName = 'uid') want retrun a "String", but the a uid is an Integer.

My send form generates an exception:

(1/1) TypeError

Return value of In2code\Powermail\Utility\FrontendUtility::getPropertyFromLoggedInFrontendUser() must be of the type string, int returned
