Attempts to Upload PageBlobs for BlobStorage and BlockBlobStorage Accounts Don't Appear to Reach Server

[jcrobins]

Storage Explorer Version: 1.6.2
Platform/OS Version: Windows
Architecture: ia32
Regression From: N/A

Steps to Reproduce:

1. Create a Premium BlockBlobStorage (or Standard BlobStorage) storage account.
2. Select the created storage account in Storage Explorer.
3. Select a container in this account in Storage Explorer and select Upload > Upload Files... to view the Microsoft Azure Storage Explorer - Upload Files to Blob Container dialog.
4. Upload a page blob.

Expected Experience:

The operation should result in an error containing the details of the ClientOtherError returned by Storage as a result of issuing a PutBlob of an invalid (PageBlob) type.
The Details of the error should contain the detailed message returned by storage for the failed operation.

Actual Experience:

Server-side logs do not indicate a PutBlob was issued.
The operation eventually fails client-side with the following error details:
{
"message": ""Upload failed unexpectedly after 5 attempt""
}

Semi-Related to the following issue (which requests we remove the "PageBlob" option for BlockBlobStorage and BlobStorage accounts):
#1170

After some investigation, this may be due to the same root cause encountered in #1050. The client library throws an error rather than calling our callback. Since it's an asynchronous situation, a try/catch block won't catch the error as expected.

Ran quick verification. Appears to be fixed after resolving #1050.
