Handle PEP479 issues on ha

Similar to how PEP479 was handled on config[1].

Instances of "raise StopIteration" were changed to
a plain 'return' statement in order to avoid breaking
the existing logic.

CentOS 7 tests:
PASS: Build & install
PASS: Successful Bootstrap

Debian Bullseye tests:
PASS: Build & install
PASS: Successful Bootstrap
