Fix TsLint defaults

[chiubaka]

Removes flags from TsLint default config, which appeared to break linting.
The "prose" option for -t is also default, so shouldn't be necessary to specify as a flag?

I'm running with tslint 5.11.0.

Without the default flags:

Running pre-commit hooks
Check for trailing whitespace....................[TrailingWhitespace] OK
Check for local paths in Gemfile................[LocalPathsInGemfile] OK
Check for "token" strings.....................................[FixMe] OK
Check if database schema is up to date..........[RailsSchemaUpToDate] OK
Check YAML syntax........................................[YamlSyntax] OK
Analyze with TSLint..........................................[TsLint] OK
Check Gemfile dependencies..............................[BundleCheck] OK
Analyze with RuboCop........................................[RuboCop] OK

✓ All pre-commit hooks passed

When overriding flags to []:

✗ One or more pre-commit hooks failed

As is, there are definitely lint errors in the working files.

Thanks for the PR, @chiubaka!

I'm not familiar with tslint so I'll defer to the original author of the hook, @jhuiting, to weigh in here.

@chiubaka @sds Haven't used the plugin myself for quite a while, but fix is OK with me.

Thanks for the fix, @chiubaka, and for the review, @jhuiting.
