array_key_exists deprecated warning on PHP7.4

[eljakim]

Expected Behavior

There should not be 'deprecated' warnings when running the software.

Current Behavior

When going to this page, I receive a deprecated warning

• http://XXX/icingaweb2/vspheredb/hosts#!/icingaweb2/vspheredb/host?uuid=XXX

Deprecated : 
array_key_exists(): 
Using array_key_exists() on objects is deprecated. Use isset() or property_exists() instead in
