[BUG] CliRunner invoke tests fail with Click 7.1

[daniel-hampton]

Describe the bug

Running tests with typer.testing.CliRunner invoke method with Click 7.1 installed results in failures with

__init__() got an unexpected keyword argument 'mix_stderr'

Forcing Click 7.0 installed fixes the issue.

Looks like mix_stderr keyword argument was removed from the invoke method.

7.0 invoke method:

    def invoke(self, cli, args=None, input=None, env=None,
               catch_exceptions=True, color=False, mix_stderr=False, **extra):

7.1 invoke method:

    def invoke(
        self,
        cli,
        args=None,
        input=None,
        env=None,
        catch_exceptions=True,
        color=False,
        **extra
    ):

Thanks! Yep, there was a breaking change introduced in Click 7.1.0.

It is now fixed and released in Typer version 0.0.10 🎉 🚀
