Reload active profiles when constructing WorkModeTile

There seems to cases when after QSTile is constructed, handleUpdateState()
is called without setListening(true) being called first. In the WorkModeTile
case it leads to the tile removing itself. The fix is to reload active profile
list in the constructor so handleUpdateState() would not remove itself because
it thinks there is no active profile.
