Previously, when toggling on background shapes, they always had the
default colours. In [1] we made it so that when you toggle on a shape on
a section, it would automatically reuse the colors of the surrounding
shapes if any.
Unfortunately, when the "implicit" colors were also the default colors,
they were still marked on the shape, and it got an explicit background
image that would no longer react to changes in the palette.
This was caused by the fact that the call to _getDefaultColors returns
an empty object when the section doesn't already have a shape-container,
this was not a problem before since we were not passing in any colors
when creating the initial shape previously, the the aforementioned
change made it so that we did.
This commit fixes the issue by creating the shape-container before
calling the method that will set the colors on the shape, this way
getDefaultColors works as expected, and the colors are not marked on the
section when they are the default ones, restoring the ability of the
shape colors to adapt to the palette
