bridge (D-Bus): fixed handling of profile in kwargs: kwargs are not handled by python D-Bus (i.e. they are not sent through D-Bus). The "profile" and "profile_key" kwargs are often used through SàT with the bridge, this was working so far because they were used for core methods (which have a signature in DBus.py handling profile), or in Libervia browser who ignore profile argument. But if the profile or profile_key was used as a keyword for plugin method outside of Libervia browser, they were ignored, this commit fix this by adding them to the args list.

Use this module to temporary store files that need to be integrated to other
projects such as Wokkel.

For example, the changeset that introduced this folder adds RSM (XEP-0059)
support to Wokkel. The files in sat.tmp.wokkel are imported over the initial
wokkel files from sat.plugins.__init__.py
