st/widget: Emit "style-changed" on all theme changes

Browse Source 
Since now the resource consumption of the "style-changed" signal
handlers should be significantly lower, we can start emitting the signal
in all cases again as it was originally intended. This fixes some small
visual issues, like the battery percentage in the panel only being shown
on hover or updating the size of StIcons on scale-factor changes.

This effectively reverts f74c07b9ac
