feat: add aliases into wait keyword for cypress tests

[lucas-louis]

[FEATURES] Add wait aliases for cypress tests

Description

In order to avoid crashed tests with cypress, because of the too long time response for the loading/ downloading/ uploading, the use of aliases into the tests will be good.

Is your feature request related to a problem? Please describe.

Sometimes, the loading/ uploading/ downloading is too long for the tests, so they crashed.

Describe the solution you'd like

The use of aliases with the wait keyword, will fix this problem.
The wait keyword could wait with a specific time (like all the tests right now) AND with a condition too, like "you wait until this event is triggered".
So instead of putting a wait of 2 seconds, for example, we could put a wait until a specific toast is displayed (the toast is the one telling that the download/ load/ upload is done)

[RezaRahemtola]

Using aliases is not needed for cy.visit() as it already waits for the page to load.

A lot of useless waits where removed so the e2e tests are now 17% faster.

I‘m closing this issue and moving the remaining part in a bullet point of #27
