fix: handle syntax error in aliased command

Browse Source 
if an alias is something which isn't valid syntax,
specifically if hilbish cant split up the input
properly to execute, it will report the error to
the user. the previous behaviour was a panic since
on error the args slice will be of length 0

this is basically an edge case and fixes a bug
which shouldnt happen normally
