SmaCC_Elixir Odd Parsing results for unary ops

[mariari]

If the operation is a unary_op I believe the Elixir parser currently gives an incorrect result.

In the picture below we can see that the + 1 matches ,2 and , arg3.

In this picture We can see && does not have the same behavior.

I'm not entirely sure why this happens, so I have no produced a fix for it.
