All calls to get_key need to be in a try/except block

[atcuno]

Nearly every plugin that calls get_key crashed in testing on at least one sample due to it throwing an exception when the key isn't paged in memory, such as:

File "/home/ub/volatility3/volatility3/framework/plugins/windows/hashdump.py", line 391, in get_hbootkey
    sam_account_key = cls.get_hive_key(samhive, sam_account_path)

    raise exceptions.PagedInvalidAddressException(
volatility3.framework.exceptions.PagedInvalidAddressException: Page Fault at entry 0xffffffff00000430 in page entry

After #1472 is resolved, we then need to audit every call to get_key to ensure it catches the invalid page exception.
