Fix issue #304

[Y-trie]

Hello Tanuj,

To fix issue #304, I've refactored the getAppsList function in Utils.kt with an extra variable: includeRegularApps. This code is now re-used for showing hidden apps. I've also refactored the inside of the function as well to make it a a bit less repetitive.

I've also gone ahead and removed getHiddenAppsList as it's no longer necessary.

I just downloaded this app a few days and have been loving it so far 😀
