`inshellisense` login shell not working

[brianferri]

Describe the bug Starting shell as a login shell breaks the autocomplete

To Reproduce Steps to reproduce the behavior:

1. Go to 'any terminal on macos' (tested on iterm2, terminal and VSCode intergrated terminal)
2. type is -l [-s <shell>]
3. See that the autocomplete does not work

Expected behavior As the normal is [-s <shell>] executes correctly and functions appropriately, I'd expect the login shell instance to work too.

Environment
