app: minor coding-style cleanup.
Adding spaces between function names and parenthese. I would normally have just amended the contributed patches and pushed, but gitlab is making our review process over-complicated with many roundtrips with contributors, and review quality drops. Stating it here for the records! See commit 70945b89 (where this cleaning should have directly been done). (cherry picked from commit 5c56f8cb)
