Showing log associated to query should work for large query logs

[jcreedcmu]

@tausbn reported being unable to view ~448M query log file from the query history, with the only message being that arising from

helpers.showAndLogErrorMessage(`Could not open log file ${queryHistoryItem.logFileLocation}`);

in query-history.ts. He says when he tried to open the same file manually, it worked. We should probably at least log the exception being handled, and if possible, show the log in some way, even if it's without syntax highlighting.

OK...reproduced. Looks like vscode handles files differently if they are opened from inside an extension vs if they are opened from inside of the main process. If opened by an extension, I assume that the editor is running in the extension's process (though haven't verified).

There doesn't seem to be an easy work around. Suggestions like this: https://github.com/mechatroner/vscode_rainbow_csv#working-with-very-big-files did not do anything different.

I'm leaning towards solving this way: notice that the error was caused by a large file and then give the user an option of revealing it in the finder/explorer.
