Fix creating actor for shared deploy TX

[carpawell]

There was a bug with reading the shared transaction, signing it, and changing signer in the original actor: #417.

Current Behavior

It was hotfixed.

Expected Behavior

A correct actor with a correct original sender should be created first. It should be rechecked and checked if there are other places with incorrect actor usage.

Possible Solution

Use a signer from the shared TX. Check that signature is correct and deploy passes.
