Object removal demo issue

[anilsathyan7]

In the demo app (openxlab) the object removal with mask changes other objects(especially complicated patters/designs) outside mask. However in the github codebase the final output is blended with original image and mask to prevent this issue.

The in-painted regions in demo looks better(compared to alpha blended code) in the local version but unmasked objects are changed in the demo.(eg. objects with shadows)
