When a Setup fails verification, it's helpful to have the exact expression that failed, rather than the default ToString() representation of the Setup class. To illustrate:

What I'd like to see in the output message:

x => x.DoThings(null)

What I actually get:

Moq.Language.Flow.VoidSetupPhrase`1[Moq.Tests.Regressions.IssueReportsFixture+IFoo]

This PR fixes that by overriding the ToString() methods and calling ToStringFixed() on the expression that is being used. This allows for a nicely formatted string representation of the expression to be returned.

Closes #810.

Generally LGTM! 👍 Just a few things for your consideration, my priority would be resolving the review comment about the changelog entry.
