Use early return on view function

[brunodles]

Just a small change to reduce the amount of indentation of these functions.

Does not introduce any other changes, just reorganize and format the code.

.. But we're returning early on minilayout 😄

What this PR is proposing is to simplify the functions.

These functions are all contained within the same if. The idea is to extract this if into some kind of validation step.

Instead of adding all the code inside of the if

void View::drawMap() {
  if (!miniLayout_) {
    // draw map code
  }//!minilayout
}

The comment at the ending bracket of the if is also a good indicator that this if is too big.

We can invert the ifs logic, and remove the indentation and brackets.

void View::drawMap() {
  if (miniLayout_) {
    // stop here
    return ;
  }
  // draw map code
}

The code of the function still the same.
If you prefer we can leave it as it is.

The deb check failed due an issue to install the required libraries.

Ohh ok now I get it, sorry I was really tired after a day at the office. :)
