Re-enable package analysis

[blairconrad]

From #1627 (comment).

Quoth @thomaslevesque:

Note: I'm not seeing the NU5048 warning on FIE when using the latest SDK (3.0 RC1), not sure why. I tried on another project and the warning does appear.

Ah, that was because of this:

FakeItEasy/src/Directory.Build.props

Line 12 in 1177af6

<NoPackageAnalysis>true</NoPackageAnalysis>

If we re-enable package analysis, there are some warnings that we should probably fix:

In FakeItEasy.Analyzer.CSharp:

• warning NU5128: Some target frameworks declared in the dependencies group of the nuspec and the lib/ref folder do not have exact matches in the other location. Consult the list of actions below:
• warning NU5128: - Add lib or ref assemblies for the netstandard1.1 target framework

In FakeItEasy.Analyzer.VisualBasic:

• warning NU5128: Some target frameworks declared in the dependencies group of the nuspec and the lib/ref folder do not have exact matches in the other location. Consult the list of actions below:
• warning NU5128: - Add lib or ref assemblies for the netstandard1.1 target framework

Oops, I mentioned the issue in the PR, but without the "Fixes" keyword... Closing manually

Whoops. I didn't notice. Thanks.
