Query stripped from endpoints

Description

RESTler is stripping query from endpoints when trying different combinations for an endpoint (the last combination). In HTTP traffic logs (network.testing.xxxx.txt), the log for such requests has the query present as 'restler_static_string' but it is not part of the actual request sent. Here is the log for an example request.

This makes the errors in speccov.json very misleading because speccov.json includes the last request combination for an endpoint and the last combination is the one with its query stripped.

The following is the log in speccov.json for the same request. The error message says that the mandatory HTTP header "x-ms-blob-type" is not specified for this request. This error does not correspond to the endpoint that is being tested i.e., "/{containerName}/{blob}?comp=seal" because it is generated for the endpoint "/{containerName}/{blob}", without query.
