Issue title: RadSideDrawer needs slow finger moving from side to open (Angular & Android)
 Issue body: **Environment**
- all NS versions
 - Android only (iOS is working)
 - Angular only (via RadSideDrawer defined in .xml instead of Angular is working, tested with Angular v7 & v8)

**Describe the bug**
Hello, I noticed that RadSideDrawer is having a "lag" or some kind of delay on Angular & Android. It's currently not possible to open the SideDrawer via moving your fingers from the side to center of the device in a "normal speed" (like expected from other apps). You have to slide your fingers very slowly to let the RadSideDrawer appear.

**To Reproduce**
The same problem happens on every ng+angular project running on Android. Create project with template `tns-template-drawer-navigation-ng` and move/slide your fingers from side to middle of the screen. You have to move slowly. 

**Expected behavior**
You can move your fingers in all speeds and the RadSideDrawer will open independently how fast you slide. For example try the "Examples NativeScript" Demo from Play Store (or github), where it's working like expected.

**Sample project**
"Examples NativeScript" App from Play Store
