Ensure builds against Cosmos DB emulator are supported

[asosMikeGore]

Need to ensure that tests are run against a consistency level of session when developing against the emulator. Pretty sure older versions of the emulator used to allow the tests to pass using bounded staleness, but this no longer seems possible.

When developing locally, ensure the consistency level is supplied in as per the example below.

.\build.ps1 -consistencyLevel Session
