"Open Query Results" button causes error: "Cannot read property 'result' of undefined"

[Marcono1234]

Describe the bug
When using the "Open Query Results" button of the Query History view an error occurs.
Button:

Log:

Cannot read property 'result' of undefined (codeQLQueryHistory.itemClicked)
TypeError: Cannot read property 'result' of undefined
	at InterfaceManager.showResults (#REDACTED#\.vscode\extensions\github.vscode-codeql-1.5.1\out\interface.js:227:21)

Note that clicking on one of the history entries opens the query results just fine.

Though to be honest, I am not sure if the "Open Query Results" button adds any value in the first place, since you would most likely first have to select the entry from the history (by left clicking?), but by doing so you already opened the query results.
