Fix tokenizer cache flushing (#7836)
* Fix tokenizer cache flushing

Fix/simplify tokenizer init detection in order to fix cache flushing
when properties are modified.

* Remove init reloading logic

* Remove logic disabling `_reload_special_cases` on init
  * Setting `rules` last in `__init__` (as before) means that setting
    other properties doesn't reload any special cases
  * Reset `rules` first in `from_bytes` so that setting other properties
    during deserialization doesn't reload any special cases
    unnecessarily
* Reset all properties in `Tokenizer.from_bytes` to allow any settings
  to be `None`

* Also reset special matcher when special cache is flushed

* Remove duplicate special case validation

* Add test for special cases flushing

* Extend test for tokenizer deserialization of None values
