Bump up the versions of the plugins that communicate with the server

This is a fix for the issue where the relative URL code on iOS doesn't work per
documentation.

Relative URL doesn't work: e-mission/e-mission-docs#732 (comment)
Appending strings does work: e-mission/e-mission-docs#732 (comment)

Includes fixes to:
- connection settings to return a string instead of a URL
    e-mission/cordova-connection-settings#22
- server-communication and server-sync to concatenate directly using strings
  instead of using a relative URL
    e-mission/cordova-server-communication#30
    e-mission/cordova-server-sync#52
