[Bug]: ts_proto_library copy sources does not support having more than one proto_library in a BUILD file

[mrmeku]

What happened?

Right now ts_proto_library uses proto_srcs = native.glob(["**/*.proto"]) to detect what generated files it should expect to copy. This is a convenient but erroneous assumption. If a particular build file has two protos a.proto and b.proto but only a.proto was used to generate a ts_proto_library this assumption breaks and you are forced to disable source copying or merge the proto_libraries together
