Overriding the thermostat temperature triggers an incompatible preset_mode

Describe the issue you are experiencing

I have an Ecobee thermostat. It seems that, at some point in time, the preset_mode supported values went from Home, Away, Sleep, Away_indefinitely to lower case versions ie home, away, sleep...

I am using the thermostat card. Whenever I change the thermostat temperature setting, an error message pops up "Preset mode is not valid. Valid preset modes are: home, away, sleep, away_indefinitely." This is confirmed in the log:
`Logger: homeassistant.components.websocket_api.http.connection

[544804952464] Preset mode is not valid. Valid preset modes are: home, away, sleep, away_indefinitely`

Using the developer tools, I am able to confirm that preset_mode went from "home" to "temp". "temp" is not a permitted value. While in the developer tools, I noticed incidentally that climate_mode was set to "Sleep" While the thermostat schedule would have it in sleep mode at this time of the day, I ponder about the capitalization.

Describe the behavior you expected

Manually changing the thermostat temperature setting should:

• change the temperature
• leave the preset_mode the way it was
  [!Note] the thermostat itself shows the current preset but indicates the override. I am not sure this is communicated in any shape or form to HA.

Steps to reproduce the issue

1. Click on the + or - button on the thermostat card to differ from the established preset
2. Notice the error message at the bottom of the screen
3. Notice that the preset on the card goes from a home icon and the text "Home" to a bullet icon and no text
   ...
