Fix oh- components cannot be configured in action modals

[florian-h05]

Fixes #927.

When attempting to open an oh- Vue component, e.g. oh-colorpicker-card, as action modal, it was not possible to configure it, even though actionModalConfig was set.
This was because oh- componens take their configuration from the computed config of the widget-mixin instead of the Vue component props.
This PR fixes that by using the actionModalConfig for the computed config of oh- components in action modals.

@ghys I have battle-tested this on my production system and I haven't noticed any regressions, so this should be safe to merge.

Can't say I have battle-tested this myself but upon reading the code it makes sense!
