Log "Warn: ignoring history value 1 (invalid)" when no history values set

[uneart]

Describe the bug
When there is no history value set, still the adapter logs warn type messages:

ebus.0 | 2021-10-20 01:54:01.904 | warn | ignoring history value 1 (invalid name)

To Reproduce
Steps to reproduce the behavior:

1. Go to instance settings
2. Click on history data points tab
3. Remove all values
4. Restart instance
5. See warning in log

Expected behavior
The warning of invalid history data is only shown if there are data points set and there is a problem when retrieving them. Otherwise there is only a debug type message saying something like "No history data points set. Skipping history data retrieval".

Screenshots & Logfiles

  Additional context
