Fix localization bug with Insider Build

[skapur12]

In the current Insider Build, even when you switch the language, the translations still display in English. This is because after the OneLocBuild task is run, then npm run clean and npm run build-translations are run in succession in Build & Pack. (Essentially all language translations are built, then all cleaned out, then only English is built.)

This PR fixes this issue by getting rid of clean:resources (which isn’t really needed anyways since the translation files are overwritten/updated on every new build). Now the translations will stay and won’t immediately be cleaned out once built.

This PR also solves the error of the translation ID appearing when you switch the language to something non-English. Before, if a string in a non-English language didn’t have a translation, it would show the ID (e.g. application.buttons.editor). Now, it shows the English string instead (Editor).
