Update tool: Patched distribution doesn't match the 7.3.0. binaries

Integration tests for the update tool don't pass. Patched distribution doesn't match 7.3.0.CR1 distribution. Seems like old deferredjs/*.cache.js files are not removed during updating.

Moreover, patch is not applicable to 7.2.0 version, which is also one of the requirements considering supported update scenarios.

From my point of view it seems that just the patch was built with wrong properties.
