`gravatar`- Investigate issue when changing values in `local.properties`

[hamorillo]

I've noticed that after merging #173, when you update a property in local.properties, the change is not reflected when launching the app.

I've verified that disabling kotlin.incremental solves the issue. But I would like to investigate more before opening a PR with that solution that will affect compilation performance.

kotlin.incremental=false

I guess K2 does something different that is not working as expected.
