* Speed up logbook and history queries where ORM rows are not needed
This avoids having sqlalchemy wrap Result in ChunkedIteratorResult
which has additional overhead we do not need for these cases
* more places
* anything that uses _sorted_statistics_to_dict does not need orm rows either
* Fallback to generating a new ULID on migraiton if context is missing or invalid
It was discovered that postgresql will do a full scan if
there is a low cardinality on the index because of missing
context ids. We will now generate a ULID for the timestamp
of the row if the context data is missing or invalid

If a user manually migrated their database to MySQL or PostgresSQL
and incorrectly created the timestamp columns as float we would
fail to correct them to double because when we migrated to use
timestamps for the columns I missed that we needed to change the
columns and types for µs precision
- If the user had previously duplicated data we could end up
picking the next metadata_id and there could be stale rows
in the database that have that metadata_id. This can only happen
from bad manual migrations (which is what this is function
is validating in the first place). To solve this we now insert
data with a future date and look at the latest inserted row
instead of the first.
Example
```
['stored_statistics',
defaultdict(<class 'list'>,
{'recorder.db_test_schema': [{'end': 948589200.0,
'last_reset': None,
'max': None,
'mean': 2021.0,
'min': None,
'start': 948585600.0,
'state': None,
'sum': 394.5068},
{'end': 1601946000.000001,
'last_reset': 1601942400.000001,
'max': 1.000000000000001,
'mean': 1.000000000000001,
'min': 1.000000000000001,
'start': 1601942400.000001,

* Fix cpu thrashing during purge after all legacy events were removed
We now remove the the index of of event ids on the states table when its
all NULLs to save space. The purge path needs to avoid checking for legacy
rows to purge if the index has been removed since it will result in a full
table scan each purge cycle that will always find no legacy rows to purge

* Avoid database executor job to fetch statistic metadata on cache hit
