Fix: Manager static ctor crashes on Azure #364

This is my official first pull request on an open source project, so let me know if I'm doing something stupid.

This patch is for #364 to allow cblite to function on a .NET web app hosted in Azure.  By enabled the .NET API to function on Azure, we are able to much more quickly generate initial snapshots of databases for mobile clients (as opposed to waiting for hundreds of thousands of records to stream down).
