Test type-resolver created from resolvecontext with:
- File containing single namespace and no block
- File containing one namespace with a block ('{}')
- File containing multiple namespaces with blocks
Patch `phpinspect--make-type-resolver-for-resolvecontext' to support namespaces with
blocks.
This commit contains one logic change: Changed add-to-list usage to cl-pushnew in
phpinspect-merge-indexes implementation for classes. The resulting function output should
be the same.
