bar2d / column2d border inconsistenies

[IssioDev]

There is an inconsistency between the plot borders on a bar2d and column2d chart which has become apparent with the 3.18.0 release.

With a column2d chart the bottom border of each column didn't exist because there was a x-axis

With a bar2d chart the left border of each bar is present, even if there is a y-axis

This also doesn't occur with a stacked 2d bar chart.,

This jsFiddle demonstrates the issue. The column chart is fine, the bar chart is not.

@IssioDevThe visualization is the same for other versions as well, if you want to turn off the border please set showPlotBorder as 0
