Removed whitespaces in macros

[JoshuaLampert]

Using the sciml style

@assert 1 == 1
@assert 1 == 1 "error"
@assert (1 == 1) "error"

gets formatted to

@assert 1 == 1
@assert 1==1 "error"
@assert (1==1) "error"

I would expect whitespaces around binary operators. I would also not expect different behavior depending on whether there is an error message or not.

This is fixed with the v2 release 👍
