Fix specs for CHROME_HEADLESS=0
This MR fixes two feature specs that fail when CHROME_HEADLESS=0
is specified.
In the Web IDE, compact mode depends on the size of window.
If it is shorter than MAX_WINDOW_HEIGHT_COMPACT, (as it is with CHROME_HEADLESS=0), the initial commit button will exist.
Otherwise, if it is taller (as it is by default with chrome headless) then the button will not exist.
