fix: use context instead of requireContext() for backward compatibility

[rohit9625]

Description (required)

Fixes #6399

What changes did you make and why?

• The app was crashing on opening certain screens because we are using the requireContext() method to retrieve context inside ContentProviders. So, I make them use the context property directly.
• I could've solved it by adding an if condition for API < 30 and using context for lower APIs and requireContext() for higher APIs. I found it redundant as both are equivalent, because the context property can be null if called before the onCreate method, and requireContext() throws an exception in the same case.
• Hence, adding multiple if conditions is just overhead.

Tests performed (required)

Tested prodDebug on Pixel 3 Emulator with API level 28.
