Right-aligned QLineEdits have different borders enabled vs disabled

[nicoddemus]

From #85 (comment), the right border is not aligned correctly when the QLineEdit is enabled vs disabled.

See the two bottom controls:

This behaviour is defined here:

qt-material/qt_material/material.css.template

Line 180 in 5a99be3

padding: 0px {{16|density(density_scale)}}px;

Removing the padding aligns the behaviour with disabled and non-disabled states. But the code to add padding based on the density value suggests me that maybe there was an issue with differents density scales... so again @YeisonCardona is the best person to apply the proper fix here.
