Check double tap when minimum scale is changed in the didChangeContentsSize().

[Title] Check double tap when minimum scale is changed in the didChangeContentsSize().
[Issue#] N_SE-49523
[Problem] The tap is not recognized in the WebApp when we do tap twice quickly.
[Cause] The two taps should be recognized correctly, but they are recognized as double tap
when Web App does not set the user-scalable to 0 and minimum scale is not defined in the viewport meta tag.
It is because the minimumScale value is calculated wrong only in the WVGA in this case.
[Solution] Check double tap when minimum scale is changed in the didChangeContentsSize().
