support transforming addons where package.name != addon.moduleName

[hmajoros]

We have a lot of addons where the name field in the package.json is different than the addon's moduleName (we like to prefix the package.json with @linkedin/, for example). This leads to issues because the codemod's telemetry helpers use package.name and moduleName for setting telemetry data and looking up telemetry data later on

in gatherTelemetry (link), the telemetry object is generated using window.require.entries, which uses the ember-cli moduleName prefix.
in getModulePathFor (link), the lookup of telemetry data is using the package.name from the package.json

After talking with @rwjblue, he suggested that we should try to use moduleName first, and fallback to name if a moduleName does not exist, something like:

addonInstance.moduleName() || addonInstance.name
