Restrict replacements of source dependencies with prebuilts
Previously, when java_sdk_library_import was preferred over a
java_sdk_library the latter ends up depending on the prebuilt child
modules created by the java_sdk_library_import instead of the source
child modules that it created itself. That was because all dependencies
on those source child modules were replaced with the corresponding
prebuilt child modules.
This change prevents those dependencies from being replaced to preserve
the dependencies from java_sdk_library onto its source child modules by
making the replacement conditional depending on the tag used. It also
updates the affected test.
