Change the isIOSOlderThan10 so it doesn't catch Chrome Webview

[neoncrumpet]

Description:

The * in the regex was catching the UA of the Chrome Webview on iOS.

Changes proposed:

• Check for an underscore after the version number

** Notes **

There might be a better regex to accomplish this.

This should fix #3846 and #3788
