Expected behavior

Custom dimensions that aren't set shouldn't appear in application insights.

Actual behavior

Under 3.0.3-BETA we can now see

{"statusDescription":""}

always appearing in the customDimensions in requests. This information was not present in 3.0.2. Note that other custom dimensions appear correctly, it is just that we have an extra unnecessary one.

To Reproduce

Steps to reproduce the behavior:
Wire up a Spring Boot 2.4.3 application with app insights and look in requests.

Sample Application

If applicable, provide a sample application which reproduces the issue.
