Update homeassistant.ts to fix template warnings

[OzGav]

Based on the issue here #8769 and the suggestion here #8617 I have added a default against all of the value and state templates.

[OzGav]

Not sure about these errors as they aren't appearing against all of my changes? Will wait for some guidance.

[Koenkk]

We decided to not use | default(''), see #6988 (review) for the rationale. Instead missing values should be set to null here: #6988 (review)

Ok but after reading all of that it seems things should have been fixed? Yet there are still people with problems. Here is mine:

Logger: homeassistant.helpers.template
Source: helpers/template.py:1612 
First occurred: 12:13:39 AM (45 occurrences) 
Last logged: 12:44:36 AM

Template variable warning: 'dict object' has no attribute 'state_button_light' when rendering '{{ value_json.state_button_light }}'
Template variable warning: 'dict object' has no attribute 'state_button_fan_high' when rendering '{{ value_json.state_button_fan_high }}'
Template variable warning: 'dict object' has no attribute 'state_button_fan_med' when rendering '{{ value_json.state_button_fan_med }}'
Template variable warning: 'dict object' has no attribute 'state_button_fan_low' when rendering '{{ value_json.state_button_fan_low }}'
Template variable warning: 'dict object' has no attribute 'action' when rendering '{{ value_json.action }}'

So is this a problem created when we did the initial setup for these switches or something else? Can it be fixed without me cobbling together templates at my end?
