Study impact of Spaces activation

[NicolasBuquet]

Spaces will be activated on web client. Study possible impact on mobile client.
Is it worth activating button "Change space"?

Spaces displaying is conditioned by a few flags :

• SHOW_SPACES in im/vector/app/config (set tot False)
• SPACES_SHOW_ALL_IN_HOME in im/vector/app/config (set to !SHOW_SPACES)
• method prefSpacesShowAllRoomInHome() in im/vector/app/features/settings (returns user defined pref or Config.SPACES_SHOW_ALL_IN_HOME if no user pref defined as in Tchap actually)

Setting `SHOW_SPACES' to True activate the Spaces button on the home list.

When displaying TimelineView coming from a notification, if Spaces are not unified (prefSpacesShowAllRoomInHome is false), the application will try to activate the space related to the room notification if no space is already activated.

Cf. im/vector/app/features/home/room/detail/TimelineVIewModel method intiSafe()

// We are coming from a notification, try to switch to the most relevant space
// so that when hitting back the room will appear in the list

When displaying unread messages, if prefSpacesShowAllRoomInHome is false, it will filter orphans rooms (rooms that are no longer in any space). (cf. im/vector/app/features/home method init())

When the setting is exposed in Settings, it will restart the activity if the value of SETTINGS_PREF_SPACE_SHOW_ALL_ROOM_IN_HOME is toggled. (cf. im/vector/app/features/settingsmethodbindPrefs()`)

And when displaying the room list, if prefSpacesShowAllRoomInHome is false, it will display only orphans rooms if no space is actually selected. (cf. im/vector/app/features/home/room/listpropertyroomListSectionBuilder`)

The impact doesn't seem big. Some conscientious testing is needed of course.

L'activation des Espaces sur Tchap Android se fait par le biais du feature flag SHOW_SPACES.
