Fix #9359; set default WCS caching to Prefer Network

- This is noted in the tool tip, but was not set. Always Cache was the
default, which caused the cache to never be updated on upstream changes.

[composer] Fix incorrect calculation of scale for tick scale bars

QPainter::drawLine(x1,y1,x2,y2) takes int values, so coordinates
were being rounded to the nearest mm. Consequently scale was way
off. Also fixes horizontal line for tick styles being drawn
incorrectly with multiple overlapping segments. (fix #10685)
[composer] Don't shrink scalebar height when updating

Previously any update of a scalebar would reset it's height to
the minimum height allowed. Now, if the user has set a height
greater than this minimum than that height is kept. (fix #10466)
