Procedures test workspace cleanup

[moniika]

The basics

• I branched from develop
• My pull request is against develop
• My code follows the style guide

The details

Resolves

Closes #4080

Proposed Changes

• Refactors tests to generate separate tests for procedures_callreturn and procedures_callnoreturn rather than use this.callForAllTypes.
• Adds try/finally blocks with workspaceTeardown where appropriate
• Removes unnecessary block.dispose calls (handled in Workspace.dispose)
• Removes unnecessary deleteVariable calls (each test has its own Workspace)

Reason for Changes

• Without separating logic into separate test calls, if test assert failed for procedures_callnoreturn (was run first) then test was not run for procedures_callreturn. This makes it easier to debug if there is a bug specific to procedures_callreturnorprocedures_callnoreturn`
• Workspaces are now always disposed even if assert fails
• Removing unnecessary logic helps simplify tests
