Fix module re-importing when inlining functions in JS BE 

When inliner reads function's body from other module, it performs
substitution _ -> moduleAlias. However, local alias can't be used
for this purpose, since call site can be in public inline function
itself, so the correct substitution would be -> _.$$imports$$.alias
