fix: issues with menu generation (#371)

* chore: adding unit tests for #366 and #326

* fix: duplicate submenu controls not generated for multiple installers

When multiple installers referenced the same expressions menu asset,
only one submenu control would be generated.

* fix: submenus incorrectly deduping across different postprocessing contexts

Fixes: #366, #326

* fix: postprocess context not being inherited into submenus (#326)

This caused issues where parameter mappings were not being applied to
submenus.
