fix(desktop/chat): Fixed finish editing msg when pressing enter

When in message editing mode was not possible to cofirm edit and
close edit mode when pressing enter key as the clicked signal
of the StatusButton is called without an argument, aparently that
signal has a var mouse parameter. Passed null as parameter to
get the signal emitted.

Closes #4213
