Rejects table name consisting of an empty string

[ghost]

The tomlkit parser rejects the following valid TOML document:

['']
x = 1

The parser raises an exception:

tomlkit.exceptions.EmptyTableNameError: Empty table name at line 1 col 3

The TOML 1.0.0 spec says about table names:

Naming rules for tables are the same as for keys (see definition of Keys above).

and about keys:

A bare key must be non-empty, but an empty quoted key is allowed (though discouraged).

From these statements, it follows that an empty quoted key is a valid table name.

This testcase is part of toml-test: https://github.com/BurntSushi/toml-test/blob/master/tests/valid/table/empty-name.toml
