This querySelector is wrong formated and raises a DOMException

[ChristianGreinke]

This code line creates a wrongly formated selector for document.querySelector and results into a DOMException

ember-pikaday/addon/helpers/pikaday.js

Line 40 in 19366ea

`td[data-day="'${day}'"]:not(.is-outside-current-month) button}`

for example day=5 gives

'td[data-day="'5'"]:not(.is-outside-current-month) button}'

which is wrong in two places the last } is too much and encasing the day placeholder with ' also brakes the selector. The right code line could look like this

`td[data-day="${day}"]:not(.is-outside-current-month) button`
