Wrap eunit macros into begin ... end blocks
This makes typos such as missing commas between two assertions (e.g. ?assert(true) ?assert(true)) syntax errors instead of silently compiling and failing with a badfun error at runtime. This won't break any existing code as parenthesed expressions and blocks have the same precedence and none of these macros can be used as patterns.
