This is small refactoring for tsconfig.json.

If the strict flag is toggled to true, several type-checking strictness flags will be toggled to true at the same time. (FYI. https://www.typescriptlang.org/docs/handbook/2/basic-types.html#strictness) Thus, if the strict flag is true, these flags are only needed when opting out. In this case, deleting these will not change anything.

• noImplicitAny
• strictNullChecks
• strictFunctionTypes
• strictBindCallApply
• strictPropertyInitialization
• noImplicitThis
• alwaysStrict
