Export button missing when viewing Space calendar

[dantefromhell]

The calendar header when viewed from a Space is missing the "Export" button.

In the global calendar view the export button is still available

The export button used to be available when viewing a Space calendar in the past, I'm not certain which version upgrade or commit changed the behaviour.

Calendar module version: 1.5.10
HumHub version 1.15.5

@yurabakhtin Any idea?

[felixhahnweilheim]

In #448 CalenderControls was removed from the filterbar view file and moved to the global view only. I think the idea was to remove the cog symbol from the spaces view and only show in the global view (to reduce confusion).

So I think this should be reverted and the CalendarControls has to differentiate between global and container view.

@luke- PR #480:

@yurabakhtin Did we remove that on purpose or was it a bug?

@luke- I think the controls were removed from the space calendar header by mistake here #447.
