[M120 Migration][TCT] Fix viewport user-scalable web-tct issue(behavior test)

Value changing of |user-scalable| property of view point meta tag is not applied
instantly. Due to this, zooming gesture is not working even if |user-scalable|
is changed to |true|. To apply this change instantly, changed to make layout
after updating |user-scalable| property.
