fix(common): ensure requests are translated to the latest version during import and search actions

[jamesgeorge007]

Description

This PR ensures requests are validated against the HoppRESTRequest versioned entity and translated to the latest version before consuming preventing any exceptions under the following scenarios.

• Importing a collection with requests conforming to an old schema followed by an attempt to open one among them via spotlight.
• Searching for a request in the collection tree with the above state (one or more requests not as per the latest schema) and selecting the request from the search results.

Fixes HFE-461.

Checks

Need to add the changes to TeamSearch.service.ts also. we use queries like getSingleRequest, getCollectionChildRequests there.

Need to add the changes to TeamSearch.service.ts also. we use queries like getSingleRequest, getCollectionChildRequests there.

Wrt the getSingleRequest function, convertToTeamTree below accounts for upgrading the requests.
Similarly, for getChildRequests function, there's an invocation of converToTeamTree happening below.
