[BUG] Quoted identifiers don't autocomplete as expected while typing

[JordanBoltonMN]

Expected behavior
I was testing some things in the language services layer. Take for example the following setup:

let
    foo.bar = 1,
    #"unneededQuote" = 2,
    #"quoted identifier" = 3
in
    |

• With no text it has the following recommendations: foo.bar, unneededQuote, #"uneededQuote", and #"quoted identifier".
• With foo. for text it has the following recommendations: foo.bar
• With any subset of a quoted identifier (eg. #, #", #"", etc) it should recommend the quoted identifier.

Actual behavior

• With no text it has the following recommendations: foo.bar, unneededQuote, #"uneededQuote", and #"quoted identifier".
• With foo. for text it has the following recommendations: foo.bar
• With any subset of a quoted identifier (eg. #, #", #"", etc) it does not recommend anything.

To Reproduce
See the setup in expected behavior

Additional context
The initial hurdle is the lexer will fail to lex if it encounters a trailing #, as it's attempting to read a keyword but fails. Instead I might want to attempt to read a keyword but fallback in starting a quoted identifier. Additionally we might need to tweak the trailing token logic to include quoted identifiers.
