SelectOneMenu: client side function selectValue() doesn't work before menu was opened

Describe the defect When calling the SelectOneMenu widget function selectValue() before the menu was opened at least once, the function call fails.

Uncaught TypeError: Cannot read property 'eq' of undefined
    at c.selectValue (components.js.xhtml?…mefaces&v=10.0.0:20)
    at <anonymous>:1:45
selectValue	@	components.js.xhtml?…mefaces&v=10.0.0:20
(anonymous)	@	VM812:1

It seems like this.items in forms.selectonemenu.js:1114 is undefined in this case.

After opening the menu, everything works fine.

Reproducer Showcase for SelectOneMenu https://www.primefaces.org/showcase/ui/input/oneMenu.xhtml

Environment:

• PF Version: 10.0.0
• JSF + version: MyFaces 2.3.6
• Affected browsers: ALL

To Reproduce Steps to reproduce the behavior:

1. Open the SelectOneMenu showcase https://www.primefaces.org/showcase/ui/input/oneMenu.xhtml
2. Execute the selectValue() function in the console for one of the menus, e.g.

PrimeFaces.getWidgetById('j_idt302:option').selectValue('Option1')

1. If you open the menu, e.g. PrimeFaces.getWidgetById('j_idt302:option').show() and then execute 2. again, it works.

Expected behavior selectValue() should be able to select a value even before the menu was opened.

I marked for Elite but its up to @sqores to implement.

Thanks for the quick fix. I just tried it with a build that includes 5a5be48 and the selectValue() function now works as expected.
