Extend the time that the loading component is visible to improve UX

[ljbroersen]

Problem

Based on Phil's comment in #1061.

Right now, the loading component is only visible for a incredibly short amount of time, which results in a not-so-great UX. To improve this, we would like the loader to be longer visible (for at least 2 seconds).

Success

On pages where the loading component is shown on refresh, the loader should be visible to the user for at least 2 seconds.

Requirements

• The loading component should be visible for at least 2 seconds.
• After those 2 seconds are over, show the page as usual.

Implementation notes

• For this issue, please don't throttle your network speed.
• The changes have to be made within the loading component.
