pgAdmin 4 commit: Fix debugger issues which could occur if one or more

Fix debugger issues which could occur if one or more of the ajax calls used to gather execution environment info
completedin an unexpected order. 

To resolve this, we have callbacks from each ajax call initiate the next one so everything is guaranteed to be
sequential.
