Fix two warnings from GCC 11

This PR resolves two compilation warnings from GCC 11

  • one is from accidentally calling empty instead of clear
  • another is a warning about this being null in an inlined call which
    is addressed with an additional check
  • [x] full local testing

Reviewed by @ronawho - thanks!
