[BUG] Default value of hidden nested components keys - not cleared from the submission when inside another edit grid.

[llaurentiu]

Having:

• A parent edit grid edited in a modal (grid 'template' has modal = true)
• Another edit grid/container inside the parent edit grid.
• A component (eg: radio/checkbox) that controls the visibility of the inner grid/container

then:

• When we show the inner grid/container by triggering the conditional
• Then we hide the inner grid/container again

=> the inner grid/container keys (the default value - [] / {}) are not removed from the submission.

Correct behavior:
components that are hidden by logic, that have clearOnHide = true, should be removed from the submission.

JsFiddle here: https://jsfiddle.net/tcLbx7pe/

happens in the last stable: 4.18.0 too.
