bitbake: data_smart: Fix caching issue for double remove references

FOO = "foo bar"
FOO_remove = "bar"
FOO_FOO = "${FOO} ${FOO}"

would show FOO_FOO = "foo foo bar" rather than the expected "foo foo".

This is actually a cache bug, this patch ensures the right value is
put into the cache. The preceeding patch adds a test case to ensure
we don't regress in future.
