TS-linting warnings about floating promises

[sauvala]

While I'm hacking Calva my ts-lister is showing warnings about floating promises on function calls of evaluateSelection in src/evaluate.ts.

Here is one of them

calva/src/evaluate.ts

Line 120 in 9193fd9

evaluateSelection(document, Object.assign({}, options, { replace: true, pprint: state.config().pprint }));

Closing since it appears the fix has been merged. Thanks @sauvala!
