fix(project): properly close window after changing directory (#3919)

## What is this PR for?

In project extra, when using `<c-w>` in the project selection menu to
change directory, the window used to show the command's exit code would
not close. This fixes it.

## Does this PR fix an existing issue?

N/A.
