if eq does not support empty strings

[wmmc88]

Describe The Bug

This is similar to #47 , but this is when the empty string is part of a conditional statement like if.

To Reproduce

This works:

e = eq "" ""
if ${e}
  # do stuff
end

This fails:

if eq "" ""
  # do stuff
end

Error Stack

ERROR - Error while running duckscript: Source: Unknown Line: 16 - Two arguments are required.

hmm seems it breaking the if/else parsing....
