(bug): httpClient is automatically parsing error responses to string since 4.4.0-RC.0 #19103
Description
I'm submitting a...
[ X ] Regression (a behavior that used to work and stopped working in a new release)
[ ] Bug report
[ ] Feature request
[ ] Documentation issue or request
[ ] Support request => Please do not submit support request here, instead see https://github.com/angular/angular/blob/master/CONTRIBUTING.md#question
Current behavior
When a post (I've only tested this method) request returns an error, like this:
{
"base": [{
"error": "something invalid"
}]
}
... the error is parsed to string even the server returns a valid JSON as above.
Expected behavior
The error response shouldn't be parsed to string.
Minimal reproduction of the problem with instructions

Just click "Send post" and take a look in the console (specifically in error... it's parsed to string).
