Wrong resolution of imported message type via root.lookup()

[80220]

protobuf.js version: master (6254efb)

Problem originates from: JennieJi/protobuf2swagger#19. I wonder if failure in protobuf2swagger is a result of a bug in protobuf.js.
proto input is:

tests/data/duplicated_defs/a/b/c/d/common.proto
tests/data/duplicated_defs/a/b/c/d/request.proto
tests/data/duplicated_defs/a/b/common.proto

Both common files contain definition of StaticRoute msg. reqest.proto imports the one from /a/b/c/d/. After conversion of proto files into reflection objects (root), root.lookUp() returns wrong definition from wrong namespace (a/b/ instead of a/b/c/d)

I pushed failing testcase into forked branch: master...80220:protobuf.js:patch/wrong_resolution
