Lack of error handling on "pass" commands

[justinsteven]

rofi-pass does not check the exit status of pass, which hides failures from the caller of rofi-pass.

This would be useful for things that wrap rofi-pass. The wrapper could take some action upon detecting a failure of rofi-pass - for example, send a notification to the user's notification daemon.

Observed behaviour

For example, if my PGP key is unavailable, then pass show results in an exit status of 2:

% pass insert test_pass
Enter password for test_pass:
Retype password for test_pass:

% pass show test_pass
gpg: decryption failed: No secret key

% echo $?
2

However, doing rofi-pass and choosing the same password from the list of passwords results in an exit code of 0:

% rofi-pass
gpg: decryption failed: No secret key

% echo $?
0

(nb. I have my rofi-pass configured with default_do='typePass')

Expected behaviour

If pass returns a non-zero exit status, then rofi-pass should:

1. Consider whether it should continue execution or bail out
2. Return the same non-zero exit status, or its own non-zero exit status
