Use of SearchedIssue and SearchedPullRequest is no longer neccesary #4098
Description
Previously, we need to wrap Issues and Pull Requests (SearchedIssue and SearchedPullRequest respectively) to additionally provide a reason to group and filter by in the former Focus view.
Currently, Launchpad uses the shared provider library to do this categorization, which doesn't make use of the reason property at all.
As a result, we can now remove the use of SearchedIssue and SearchedPullRequest and access Issues and Pull Requests directly, reducing unneeded indirection and complexity.
