Allow logical expression in if statement - #43

Consider these two code-snippets:

if (window && !window.customElements.get("foo-bar")) { window.customElements.define("foo-bar", class extends HTMLElement {}) }

if (window && window.customElements.get("foo-bar")) { window.customElements.define("foo-bar", class extends HTMLElement {}) }

In both cases, the if statement has the type LogicalExpression, which we weren't checking for in our lint rule. Additionally, in the former snippet, the customElements.get call is a UnaryExpression and gets handled by our existing code. Still, the parent is just a LogicalExpression in the second snippet. So we make sure to not register the element if its parent is a LogicalExpression.
