Card not aware of alternate pressure sensor unit

[ki4hrg]

Describe the bug
When using an alternate entity for pressure, if the unit for that sensor is set to hPa some conversion happens on the card (apparently it's attempting to convert from inHg to hPa rather than recognizing that the unit is already hPa based on the correct value being displayed if the option to convert to inHg is chosen).

To Reproduce
Steps to reproduce the behavior:

1. Set the units for a sensor returning pressure to hPa.
2. Choose that sensor as an alternate entity for pressure.
3. The incorrect pressure is displayed on the card.

Expected behavior
The card would recognize the unit for the alternate sensor.

Screenshots
(1012.xxx is the value of the sensor entity)
