The bug was caused by markAndReplaceFor not running the code to preserve the selection after
text replacement only when smart quote is enabled. Furthermore, when smart link was disabled,
we never applied smart quote due to the following condition at line 2502:

if (!(shouldPerformReplacement || shouldCheckForCorrection || shouldMarkLink) || !doReplacement)
    continue;

This condition prevented the code to apply smart quote from running when both continuous
spellchecking, smart link, and text replacement are disabled.

Fixed the bug by treating smart quotes and smart dashes like any other text replacement and set
shouldPerformReplacement to true whenever either one of those text checking options are present.

Smart link didn't have this issue due to the explicit check for shouldMarkLink.

Smart dashes didn't suffer this problem either because dashes replacement happens only once
the caret has moved past the dashes but his patch makes go through the same code path to preserve
the selection as well for consistency.

Added a regression test for smart quote under all combinations of
spellchecking and substitution configurations.
