Enable strict mode

[daboudii]

After reading this Angular blog post, I thought it would be nice to make your starter app in strict mode.

Describe the feature you'd like:

Enable stricter type checking in tsconfig.json:

• strictPropertyInitialization
• strictNullChecks
• noImplicitAny
• strictBindCallApply
• strictFunctionTypes

Reduce Bundle Budgets:

• 500KB warning and 1MB error budget for the initial JavaScript we send to the browser
• 2KB warning and 4KB error budget for the styles of any component

Other information:

"strictBindCallApply": true, do not cause compilation errors.
the rest of them does fail compilation.

I would be willing to submit a PR to fix this issue:

[] Yes (Assistance is provided if you need help submitting a pull request)
[x] No
