Hover popup shows horizontal line

[rchl]

Describe the bug
Don't have time to look at it now but LSP-json shows some unexpected content (line) at the bottom of the hover popup:

Latest everything at the time of reporting.

Setting "show_symbol_action_links" to false will fix the issue.
This was introduced in #1974

Didn't looked closely at that PR to see what exactly causes this :)

I looked closely and the bug is somewhere here around this line
https://github.com/sublimelsp/LSP/pull/1974/files#diff-e572bef24745eb3ac503d83266340c8f98d60cf6e2d1ae91b0628370af45ac58R280

        if userprefs().show_symbol_action_links and contents and not only_diagnostics and hover_content:
            symbol_actions_content = self.symbol_actions_content(listener, point)
            if link_content and link_has_standard_tooltip:
                symbol_actions_content += ' | ' + link_content
            elif link_content:
                contents += '<div class="link with-padding">' + link_content + '</div>'
            contents += '<div class="actions">' + symbol_actions_content + '</div>' # hot spot, line 280 :)

symbol_actions_content value is an empty string on line 280

Looks like putting the last line under a if symbol_actions_content: will fix it.

And I think there is another bug: in case there is non-empty link_content, but no other symbol_action_content, then there will be an unneeded vertical spacer | at the beginning. I can make a PR to fix it.
