Error with unary expression #4
Description
Thank you for your gulp-unassert!
I'm not sure that unassert's responsible for this issue, but I record.
This is a minimum sample to occur the error.
function add (a, b) {
!console.assert(a)
return a + b;
}Error:

type = expr.type || Syntax.Property;
^
TypeError: Cannot read property 'type' of null

I got this error through JS includes jQuery.
e.g. https://github.com/jquery/jquery/blob/5c4be05d3b32456553dc944853b77fa96ae8b2b8/external/sizzle/dist/sizzle.js#L2155
Thanks!

@tgfjt Thank you for using unassert, thank you for reporting, and thank you for creating minimal reproduction case.
Yes, this is a bug. I'll fix it ASAP.
