Fix Javascript / Typescript template strings

[pokey]

Saying "take string" inside a template string should work. Also worth testing a tagged template. So saying "take string" within either of the following lines should take everything but the ; on the given line:

`foo ${bar}`;
taggedTemplate`hello ${firstName}`;

take string inside foo ${bar} appears to be working for me. Could you elaborate?

Strange. Pretty sure I tested it and it didn't work. @Will-Sommers is this one still not working for you? I believe you originally raised this issue in #641

When the cursor is within the taggedTemplate keyword, nothing happens. I think that the expected behavior should be that the entire line, apart from the ; is selected.

Taking a look at the typescript.ts string definition, it seems like template_string is defined and it is the same type whether for a tagged template string or a regular template string. I think that we need to add the ability match either from the name of tagged template's function identifier or the template_string itself.

Here's the parse from when the cursor is within taggedTemplate from this code:

`taggedTemplate`hello ${firstName}`;

> program
>> expression_statement
>>> call_expression
>>>> function: identifier
>>>> "taggedTemplate"

and within the template string itself:

program
>> expression_statement
>>> call_expression
>>>> arguments: template_string
>>>> "`hello ${hello} world`"

Here's a quick breakdown:

code	cursor position	correct behavior
`foo ${bar}`;	within template string	✅
`taggedTemplate`hello ${firstName}`;	within template string	✅
`taggedTemplate`hello ${firstName}`;	within tagged template function	❌
