Update gradle build

[piotrilski]

The reason of this PR is the error I was getting when trying to build my app for android:

Failed to build plugin nativescript-google-analytics : 
Error: Command failed: ./gradlew -p /Users/piotrilski/workspace/beachyapp/client-nativescript/platforms/tempPlugin/nativescript_google_analytics assembleRelease -PcompileSdk=android-27 -PbuildToolsVersion=27.0.1 -PsupportVersion=26.0.0-alpha1

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/piotrilski/workspace/beachyapp/client-nativescript/platforms/tempPlugin/nativescript_google_analytics/build.gradle' line: 58

* What went wrong:
A problem occurred evaluating root project 'nativescript_google_analytics'.
> Could not find method classpath() for arguments [com.android.tools.build:gradle:2.1.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Changes:

• added src/node_modules/ to .gitignore (that's why the amount of changed files is 1.6k +)
• updated to NS 4.0
• bumped version

No worries, just ran into this when I upgraded to TNS 4.0. Thanks for this awesome plugin btw.
