Errors in translation of BETWEEN expressions with quoted operands when tidyverse = FALSE

[ianmcook]

When tidyverse = FALSE, translations of BETWEEN expressions with quoted literal strings or quoted column names as their operands might be erroneous and might cause warnings. This happens because the replace_special_keywords() function outputs a string that has more instances of MASKING_CHARACTER in it than the input string did, so the unmasking code cannot correctly replace the masked quoted strings.
