Clean up all useless async/await statements

[maikdevries]

Is your improvement request related to a problem? Please describe.
Not necessarily a problem that occurs due to this but to ensure a high-quality codebase, useless async/await statements should be removed as they are simply clutter.

Describe the solution you'd like
Go through the codebase and remove async statements where await is not used.
