Don't throw "unprocessed input" error as consequence of another error.

[kareltucek]

Steps to reproduce:

• Make some errors in your macros and save config.
• Observe that every error is followed by a redundant "unprocessed input" error.

E.g.:

Warning at Emoji 2/1: `@` notation is now deprecated. Please, replace it with $currentAddress. E.g., `@3` with `$($currentAddress + 3)`.

Error at tstErr 1/5: Unrecognized command: abcdefg
> 5 | ifShortcut abcdefg
>   |            ^
Warning at tstErr 1/5: Unprocessed input encountered.
> 5 | ifShortcut abcdefg
>   |            ^
Error at tstErr 1/6: Unrecognized command: defg
> 6 | ifGesture defg
>   |           ^
Warning at tstErr 1/6: Unprocessed input encountered.
> 6 | ifGesture defg
>   |           ^

Correct output:

Warning at Emoji 2/1: `@` notation is now deprecated. Please, replace it with $currentAddress. E.g., `@3` with `$($currentAddress + 3)`.
