1. Updated dependencies.

2. Preserve query string params inauthorizationUri (Fixed#144 with#153).
Now whenauthorizationUri contains contains query string parameters, they are preserved ongetUri methods calls.

Affects methods:ClientOAuth2.token.getUri,ClientOAuth2.code.getUri.

E.g. havingauthorizationUri=https://example.com/foo?bar=qux and callinggetUri method, the output would be:
Before:https://example.com/foo?bar=qux?client_id=....
Now:https://example.com/foo?bar=qux&client_id=....

3. Do not send empty scopes to an auth server (Fixed#98 with#154).
Ifscopes is set to"" or[] then we send an empty string to an auth server. Ifscopes is undefined (not set), then we don't send it at all.

Affects method:getUri,ClientOAuth2.owner.getToken,ClientOAuth2.credentials.getToken,ClientOAuth2.jwt.getToken,ClientOAuth2.token.getUri,ClientOAuth2.code.getUri.
