Bash completion partly broken for bash 5.0.7

[sublibra]

When selecting engine through the -e flag the code completion breaks. If engine is supplied through a corectl.yml file the issue can't be found.

example

$ corectl -e localhost:29076 -a ⇥⇥
<prints local dir>

with corectl.yml:

engine: localhost:29076

$ corectl -e -a ⇥⇥
<suggests app>

$ corectl -e localhost:29076 -a ⇥⇥
<prints local dir>

Issue found on Bash 5.0.7 (darwin)
The issue can't be found in bash 4.4.19 (bash win)

Issue can't be found in bash 3.2.57 (Darwin)

Reproduced on the restructuring branch (using -s instead of -e)
