fix: do not clear ably client on reset

[ttypic]

Looks like it unnecessary to delete ably client on reset, it breaks push logic

[sacOO7]

I would be honest, this push.reset() itself feels like breaking the state machine as mentioned here ably/ably-flutter#479 (comment).
Spec mentions proper flow of activation state machine. Every stateChange reflects in a flow that can go in different directions.
https://sdk.ably.com/builds/ably/specification/main/features/#RSH3.
I think right solution would be to provide a stateChange that is a part of activation machine and should resemble called deactivate

[sacOO7]

You can try and check if the hacky solution works!
It shouldn't introduce a state where it disrupts the natural flow of the activation machine though!

Yes, this PR is just healing the symptom not the original problem
