Noisy DeploymentManager exceptions in 1.8 Exp 2

Describe the bug

In 1.8 Exp 2, the Deployment Manager is now included in the app by default, rather than requiring developers to manually call it. However, DeploymentManager.Initialize (in DeploymentManagerAutoInitializer.cs) throws a noisy (non-fatal) exception during startup, i.e.

Exception thrown at 0x00007FFF80C56798 in app.exe: Microsoft C++ exception: 
wil::ResultException at memory location 0x0000002D3619B750.

The output window shows:

Exception thrown at 0x00007FFF80C56798 (KernelBase.dll) in app.exe: WinRT originate error - 0x80070057 : 'The parameter is incorrect.'.
C:\__w\1\s\dev\Deployment\DeploymentManager.cpp(312)\Microsoft.WindowsAppRuntime.dll!00007FFE8E3834A8: (caller: 00007FFE8E3834FC) Exception(1) tid(4990) 80070057 The parameter is incorrect.

Steps to reproduce the bug

Install Windows App SDK 1.8 Exp 2, use single-project MSIX mode (EnableMsixTooling=true) and launch the app packaged.

There shouldn't be exceptions during launch

Reproduce with Windows App SDK 1.8 Experimental 2 in a single-project MSIX app using EnableMsixTooling=true. Start with DeploymentManagerAutoInitializer.cs and DeploymentManager.cpp around line 312, then verify that packaged app startup no longer emits the reported non-fatal exception.
