Fix macro resolution

[Cyberghxst]

Description

This pull request fixes an accidentally introduced bug in macros feature.
It basically were replacing every "#word", "# word" to an empty string, that wasn't intended to happen.
Now it replaces the possible macros in the code only if theres ones cached and checks if the current macro exists, if they don't skips to the next match.
