let replacement access all data like {url}

[laoyuan]

Now you can:
php artisan notifynder:create:category "post.comment" "{from.name} leave a comment to <a href=\"{url}\">your post</a>"

In this case you can simply remove the array_filter() the mixedGet() checks for this and if it returns an empty value it doesn't replace anything.
This will save a bit of logic.

After this change can you please add/extend unittests to cover the new logic/possibilities.

@Gummibeer I think array_filter() is necessary to check, so I just add a test.

[Gummibeer]

To check what? The mixedGet can't return a not existing value.

[laoyuan]

@Gummibeer I don't want to remove all {xxx}, so check if xxx is a property name first.

Ok, cause there could be a case when this is part of the real message - now I got it, thanks!
I will take a look at it and extend the unittests and will merge it.

is already implemented in v4 - cause of inactivity I will close this PR.
