Dark version of default theme always trigger the pager

[FreddieOliveira]

Description

When using the dark version of the default theme, every command output is displayed by the pager, even if it fits on the screen.

Steps to reproduce

1. Add syntax_style = default -dark to your config file
2. Open chinook db in litecli and enter the select * from genres limit 1 command

Expected result

The output should be displayed without being handled by the pager, since it fits on the screen

Actual behavior

The output is displayed on fullscreen by the pager program

Additional info

Despite being similar to #94, these issues aren't the same, since using the default theme without the -dark variant doesn't cause this problem.

This issue also causes the table to be vertically formated if auto_vertical_output is set to True even when not needed (it fits horizontally on the screen).

Probably fixing #94 will also fix this.
