[FIX] mail: pass props to thread actions

Since [1] thread actions are stored in a specific registry.
Some of those actions require props to be passed to their
component.

Those props are not correctly passed as the `componentProps`
key is in fact a function that returns the props but is
treated as the props themselves.

This commit fixes this issue by transforming `componentProps`
into a getter, so that `action` is internally passed to
`componentProps` definition. The templates using thread
actions can still use `t-props="componentProps"` as getter,
as the active action is deduced by transform automatically.
