[REG] Right click in 3D view does not deselect components

Found issue:

Right clicking in some empty area of 3D View does not deselect selected components as it should.

Steps to reproduce:

• Create a 3D project
• Select some component(s) either by clicking in 3D View or in Navigator
• Right click somewhere in 3D view (not on top of any component)
• -> Selected components are not deselected and opened context menu shows options for those components (e.g delete, copy...)

Additional information:

Was still working correctly in test round run March 7th. Squish has some issues deleting cameras and lights using context menu since then, might be related to this issue.
