Mkdocs-material: Exception when setting only logo icon in 5.0.0rc1

[frankie567]

__I checked that...__

• [x] ... the documentation does not mention anything about my problem
• [x] ... the problem doesn't occur with the default MkDocs template
• [x] ... the problem is not in any of my customizations (CSS, JS, template)
• [x] ... there are no open or closed issues that are related to my problem

Description

In the configuration, when specifying a custom icon as logo, but not a custom repo icon, a jinja2.exceptions.TemplateNotFound is raised.

Expected behavior

The logo icon should be set, and the repo icon should fallback to the default.

Actual behavior

A jinja2.exceptions.TemplateNotFound is raised. As a workaround, we can set the repo icon the configuration.

Steps to reproduce the bug

1. Start a mkdocs-material project
2. Set this in the theme configuration:

theme:
  name: 'material'
  icon:
    logo: fontawesome/solid/microphone

1. Run mkdocs serve

Fixed in fcbd47c2, will be part of RC 2. We'll wait for some more feedback before the next RC, as this is a minor bug with a simple workaround for the time being.
