Refresh data after SpaceApi URL change

[mikini]

When directly editing SpaceAPI URL in the "Current hackerspace API" setting (after commit 39cd9b1 it is called "Edit SpaceAPI URL") data from the new SpaceAPI isn't reloaded as would be expected when returning to the main page.

First when manually pushing the reload button data is reloaded or an error is thrown.

Tested on latest release 1.8.2 from F-Droid but I see no later commits which seem to address this.
