The code for props validation assumed that the rendering context was a
component. This was actually true when it was written, but is no longer
true since t-call-context was introduced.
Because of that, it would crash when trying to access the internals of
the component, such as the static components object.
The fix is simple: instead of passing the context to the props
validation code, which can now be anything, we pass the component node,
which is guaranteed to give a reference to the component (and also to
the app). This also make the code slightly simpler.
closes#1261
Have a Component which has a Component node, and a dynamic t-call itself having
a Component node.
Before this commit, both children had the same `key`, (as in the key in parent.children, which registers on the parent all its children).
As a result, the scheduler was endlessly hanging.
After this commit, it works as expected.
