CRS customization

[EmirCaldeira]

I found a bug when i tried to customize CRS. I tried putting the parameters to create a new CRS to Albers Projection with instructions for Instituto Brasileiro de Geografia e Estatística (IBGE), organization responsible for cartographic brazilian policies. QGIS returned me the following bug:

*"Custom Coordinate Reference System Cannot save 'SRC gerado (+proj=merc+lon_0=0 +lat_ts=0 +x_0=0 +y_0=0 +ellps=WGS84 +units=m _no_defs)' - this Proj string definition is equivalente to ESRI:54004. Try changing the CRS definition to a WKT format instead"**

I'm using QGIS 3.10.4 and win10 64 bits The parameters i tried to use were: "+proj=aea +lat_1=10 +lat_2=-40 +lat_0=-25 +lon_0=-50 +x_0=0 +y_0=0 +ellps=WGS84 +datum=WGS84 +units=m +no_defs"

Follow the instructions in the warning and change the format drop down to "wkt"
